Unfortunately, when the main county-scale map is interacted with, the layer visibility changes are not made on the community-scale inset map.</P><P></P><P>Does ArcMap have any functionality to achieve the desired: a link between the two dataframes which toggles the visibility of a layer as it's copy is toggled in another data frame.</P><P></P><P>I am not afraid to get my Python hands dirty, so if there is a hack I can achieve that can be then distributed to clients and function properly, I'm all ears.</P><P></P><P>Thank you for your help,</P><P></P><P>Kevin Henry</P></BODY></HTML> Tue, 10 Feb 2015 20:44:12 GMT https://community.esri.com/t5/mapping-questions/link-layers-from-two-data-frames/m-p/647083#M7059 KevinHenry1 2015-02-10T20:44:12Z Re: Link layers from two Data Frames? https://community.esri.com/t5/mapping-questions/link-layers-from-two-data-frames/m-p/647084#M7060 <HTML><HEAD></HEAD><BODY><P>You could use a combination of the following to build something in python:</P><UL><LI><A href="http://resources.arcgis.com/en/help/main/10.1/index.html#/ListDataFrames/00s30000001p000000/">arcpy.mapping.ListDataFrames</A></LI><LI><A href="http://resources.arcgis.com/en/help/main/10.1/index.html#/ListLayers/00s30000002n000000/">arcpy.mapping.ListLayers</A></LI></UL><P></P><P>You would need to be able to identify your layers in each data frame (by name, description, etc).
